ibmvfc_reset_host(9)

💖 ibmvfc_reset_host 💖

okay so bestie, welcome to another page of the Kernel API Manual — yes that's the manual name, and yes it's exactly as iconic as it sounds 🎀. This one's a tiny little function with a very big job, and honestly? It ate.

---

✨ NAME ✨

ibmvfc_reset_host — reset the connection to the server

That's it. That's the whole gig. It resets the connection to the server. No cap. 💅

---

🌸 SYNOPSIS 🌸

void ibmvfc_reset_host (struct ibmvfc_host *vhost );

Look at that return type. void. It gives nothing back, because it's a giver. It does the thing and it doesn't need applause (though it deserves some, lowkey 🫶).

---

🦋 ARGUMENTS 🦋

• vhost — the ibmvfc host struct. that's it. that's the one argument. it's the host struct for ibmvfc and our girl needs it to know which connection she's resetting 💫

---

⭐ SEE ALSO ⭐

okay so this is the part where I need you to sit down, hydrate, and brace yourself 🍓. This function is part of a whole lil ecosystem, and the manual lists every single one of its friends. Every. Single. One. We do not skip, we do not summarize, we list them all — that's the vibe check and we passed it 💯

First, the file where the magic lives:

• Kernel file ./drivers/scsi/ibmvscsi/ibmvfc-core.c

ngl bestie, notice how the list starts without ibmvfc_trc_start(9) on the same line as the kernel file — the manual has it tucked onto the first line of the list itself. Copy it exactly as it is, don't get cute with the formatting when you're typing it into code 🙈

and that's the whole page! from the ./drivers/scsi/ibmvscsi directory, October 2026 edition, mwah 😘 go reset that connection, you absolute main character — slay 🦋💜✨
